Generally, it is an object of this invention to provide for a novel formof socket, comprising a carrier element, having therein, a series ofchambers, into which resilient con- 1 tacts are adapted to bepositioned, which resilient spring contacts are adapted to be soarranged, as to provide for direct resilient contact with the prongs, ofthe element, supported by the socket, which prongs pass throughapertures, formed in the upper surface of the carrier, at a point, andin the proximity of the chambers within the carrier.

Specifically, it is aimed to provide for a novel form of socket, havinan insulating carrier plate, to which there is adapted to be fixedunitary flexible strips of metal, stam ed so as to have angularlydisposed and 0 set ortions thereof, positioned within chambers in thesocket, and contacting with prongs of electrical instruments such asvacuum tubes, de ending in said chambers, the strips being att hablecentrally, of their length, to the ca: 181 plate, which is positioned atthe base of the socket, the lengths of the strips extending from thepoint of fastening thereof to the carrier, being adapted to pass throughgrooves within the base of the socket, for providing terminalconnections with the remaining elements of the radio receiver.

till further, it is aimed to provide for a novel form of socket, inwhich a carrier member has positioned conductor members thereon of whichcontact portions extending upwardly therefrom, into chambers formed inthe body of the socket, whereby pressure contact with the prongs of anelectric circuit depending from the top of said socket, is made, thefree ends of the respective conductor members being adapted to beextended radially of one another, along the carrier,

and passin through grooves formed on the outer perip cry of the base ofthe socket, so as to provide for insulation of the conductors from oneanother, and for proper terminal 1928. Serial No. 285,517.

Referring to the reference characters in the drawings numeral 10, reresents a casing formed of a phenolic con ensation roduct, and hollowedinteriorly as at 11, an con taining a series of chambers 12, extendingupwardly from the base towards the top of the casing, as shown in Fig.3, and terminatin adjacent the top 14 of the casing, in whic there areformed a series of apertures 13, leading from the top 14 of the casinginto the chambers 12, the apertures 13, being cylindrical within the topof the casing and being adapted to assume a semi-cylindrical form, alonthe length of the chambers, whereby portions of the prongs 15, of avacuum tube 16, or other electrical element, will be positioned withinthe cylindrical cut out portion extension of the aperture 13, while theother halves of these prongs, will project into the chamber 13 proper,for contacting with the conductors, the function of which will be laterdescribed.

A hub 17, is formed centrally of the casing,

and projects downwardly therein for a greater portion of its depth,there being adapted to be passed through an aperture 18, 1n sald hub, aneyelet here being indicated as the preferred fastening means formamtammg the base cover 20, and carrying the conductor is observed thatthe carrier or cover member 20, comprises of a flat disk formedpreferably of a phenolic condensation product, having a series ofapertures 21 therein, through which eyelets 22, may be passed for fixingthe contact members 21 thereto, in a manner to be later described.

A central aperture 23, is formed within the carrier, for providing formeans, whereby the eyelet 19, may be passed through .for fastening thecarrier to the casing, at the hub portion 17 thereof. A cut out portion24, is formed on the outer periphery of the carrier 20, which apertureis adapted to have fit therein a rojection 25, formed on the innersurface 0 the casing 10, whereby the carrier with the conductor members21 thereon, may be readily and easily positioned in the hollow portion11 of the casing, so that the flexible contact portion of the conductorsmaybe properly positioned within the chambers 12, with a minimum ofeffort, and so that once the carrier with its conductors is positionedin assembled relationship, it cannot be ro-- tated.

Referring to Figures 3, 4, 5 and 6, it is seen that the conductorcomprises a length of flexible metal, either tin, brass or aluminum,having a base portion 26, adapted to rest flat against the carrier 20,and having a plurality o apertures 27 and 28, of which 28, is adapt- 1ed to be aligned with the apertures 21, in the carrier, and throughwhich an eyelet 29 is adapted to be passed to fix the conductor to thecarrier; the aperture 27 formed at the extremity of the flat portion ofthe conductor being adapted to form the contact terminal with theremaining elements, with which this device is applied. Ofi'set andangularly disposed of the base portion 26 of the conductor, there isadapted to be formed the pressure head of the conductor, comprising aprong contact portion 29, at right angles to the base 26 of theconductors, and the wall contact portion 30, the wall contactportionforming the extremity of theconductor, being bent over uiponitself to form an angularly disposed exiblep essure contactingortion-,cooperating wit the wall of the c amber 12, as shown in Fig. 4,and the portion 29, being adapted to be contacted by the prong 15, as

' shown in Fig. 4. A cut out portion 31, is

formed in the conductor and extends for a portion of the length of theoffset portion 29, and the flat. portion 26, the purpose of thisaperture being to provide for facility in bending the conductor intoposition, and simplicity in structural formation thereof.

' When the carrier 20, with the projecting resilient conductor portions21, is assembled as in Fig. 5, this assembled section of the deviceisforced into the hollow ortion 11, of the casing 10, asshown in Fig. 2,to provide for the structure shown in Figure 1, there being formedin thebase of the casing, a series of channels 32, through which theextremities of the flat portion'26, of the conductors may pass forinterconnection, to provide for the terminal connection of the socket,the said flat portion 26, of the conductor being adapted to extendconsiderably above the base'of the casing, so as to prevent theconductor from contactingwith any other conductors or devices within theradio receiver, which may be extended on the base or subpanel of'thesame, adjacent the socket.

As seen in Figures 2 to 6 inclusive, the conductor member 26, is adaptedto have the contact portion 29 of the flexible pressure portion 30,formed integral therewith, positioned Within the respective chambers 12,wherein the depending prongs 15 of the vacuum tube or other electricaldevices, are adapted to be insertable with one half or equivalentfraction of the prong, being positioned in the groove 13, formedadjacent-the chamber, and the other projecting half, thereof, contactingwith the contact portion 29 of the conductor, spaced from the opposingwall by the flexible pressure member 30, formed integral therewith.

The angular groves 32, formed in the base of the casing are disposedangularly of the chambers 12, so that the flat portion 26, oftheeonductor 21, oflset from the contact por-- tion 29 thereof, may beretained in fixed position in the casing, for providing the terminalcontacts with the remaining elements of the receiver through theapertures 27 thereof. Apertures 33 and 33' are provided in the base ofthe casing, for the passage therethrough of the fastening means to fixthe casing to a subpanel or any part of the receiver to which the socketis desired to be attached. I

It is obvious that various changes and modifications may be made to thedetails of construction without departing from the general spirit of theinvention as set forth in the ap pended claim:

What I claim: A socket for a vacuum tube, comprising a casing having aseries of chambers formed interiorly thereof adjacent its periphery, ap-

ertures disposed in the top of said casing, forming the termination ofsaid chambers, an aperture formed centrally in the top of said casingand merging into a smaller aperture extending to the base of saidcasing, a carrier late positioned at the base of said casing orenclosing the chambers therein, resilient conductor members positionedin the respective chambers for contacting with the prongs of a vacuumtube passing through the apertures leading thereto, said conductorsbeing fixed intermediate their ends to said carrier member and extendingradially from said carrier member for forming contacts with elements ina radio circuit, said conductors being adapted to rest in cutoutportions along the periphery of the casing at the base thereof, anaperture disposed centrally of said carrier in line with the centralaperture of the casing, and a rivet for fastening the casing and saidcarrier at their central apertures, and a cutout portion on the outerperiphery of said carrier, and a projection in the base of said casingfor positioning the carrier, so as to locate the contact members intheir proper chambers, and to prevent displacement thereof.
